Public bug reported:
I'm using a Raspberry Pi 3B running Ubuntu Server 20.04 arm64. If I try
to compile a systemtap file which probes "signal.send", I get multiple
definition warnings, and compilation fails because stap passes -Werror
to the compiler.
ubuntu@pi-ubuntu:~/bin$ cat empty.stap
probe signal.send {
printf("signalled\n");
}
probe begin {
printf("hi\n");
}
ubuntu@pi-ubuntu:~/bin$ sudo stap empty.stap
